Good luck Blondie. I had synto drip after my waters went at 40+15, but I didn't go into active labour within 24 hours. No pessary, straight onto synto. It wasn't too bad at first - mw increased the drip gradually, and then turned it down once contractions were well established. I was managing on paracetamol and gas and air. However bitch of a doctor then turned the drip back up, and things fell apart a bit. I had morphine, was examined and only at 4cm so I asked for an epidural; by the time they were ready to give it, I had fully dilated really quickly and wanted to push! Didn't push for too long, but went for it big style - luckily didn't have any tears, just a few grazes, and DS was 8lb 12. 7 hours 10 mins from being first hooked up to the drip.
I was continuously monitored, and v v cross at bitch doctor who insisted on putting a clip on DS's head in the later stages. TBH, I had thought I would want to be active, but when it came down to it, I stayed on the bed sitting up, and then onto my side.
The whole thing was the exact opposite of what I hoped my birth would be, but do you know what, with the help of two fab midwives, it was fine, and we both came out of it pretty unscathed. This is my only birth, so nothing to compare it to.
Hope it goes well for you.
